This is a musical number from the TV series, Crazy Ex-Girlfriend. I've never seen the show, but checking some details out, it seems as if they do a lot of musical sequences on the show.
There are a couple of small tidbits worth nothing. In addition to two-time Tony Award-winner Patti LuPone – who's very good in the scene, but particularly funny for not being Jewish, though playing a rabbi's wife here – the other “mother” in the scene (who joins her at the :39 mark singing and dancing about the Holocaust is Tovah Feldshuh, who's a semi-regular on the show (as the mother of the main character) and also has a very long Broadway career, with three Tony nominations, and among for many credits starred as “Yentl” in a short-lived stage adaptation of the story. And most recently she was in the current revival of Pippin. So, the TV show got some pretty good names for the sequence.
